Mechanical Engineer (Data Center Infrastructure)

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars. SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next. ABOUT THE ROLE: As a member of the facility operations team, you will help design, build, activate, and maintain some of the world’s most technically advanced facilities and data centers. You will be able to operate with autonomy to solve diverse and complex problems, excel at managing multiple projects at a time, and work in a dynamic, fast-paced environment. As a Facilities Engineer, you will coordinate and execute infrastructure projects as well as oversee ongoing operations and maintenance of facilities, equipment, and utilities. This will involve corrective, preventive, and predictive maintenance techniques as well as operational and design feedback for maintaining and improving all systems at our Memphis and Southaven sites. RESPONSIBILITIES: Lead internal project teams, consulting engineers and contractors throughout the entirety of the MEP engineering, procurement, construction, commissioning and maintenance process. Provide technical engineering support/information to ensure construction/maintenance complies with all standards, codes, and specifications. Verify maintenance is being completed and coordinate all repair, build, and contingency systems efforts for HVA

ABOUT THE ROLE: As a Sr. Facilities Operations Technician at SpaceXSI, you'll dive in, operating and maintaining the critical facility systems that power our supercomputing data centers. Working hands-on with MEP systems, you’ll tackle maintenance, operations, and repairs, ensuring peak performance and reliability. Expect to troubleshoot complex issues, streamline processes, and collaborate with teams to keep our infrastructure running smoothly, directly supporting xAI’s mission to accelerate human scientific discovery through AI. RESPONSIBILITIES: Independently operate and maintain critical mechanical, electrical, and plumbing (MEP) systems in supercomputing data centers, ensuring high reliability and performance through hands-on maintenance, troubleshooting, and process optimization. Perform advanced maintenance and troubleshooting of critical data center systems like HVAC, power, and environmental controls, while mentoring junior technicians to ensure operational reliability. Oversee the maintenance and optimization of critical data center infrastructure, including power, cooling, and environmental systems, while leading a team of technicians to ensure operational relia

ABOUT THE ROLE: As a member of the SpaceXSI construction team in Memphis, you will design, build, and activate some of the world’s most technically advanced electrical infrastructure — from high-voltage substations through medium-voltage distribution to low-voltage data center power systems and Battery Energy Storage Systems (BESS). We execute complex electrical construction projects and infrastructure improvements from cradle to grave. You will operate with autonomy to solve diverse and complex power-system problems, excel at managing multiple projects at a time, and work in a dynamic, fast-paced environment. You will work with other construction engineers, electrical contractors, equipment vendors, utilities, architects, and internal customers to deliver reliable, high-capacity electrical systems that support AI-scale compute. All SpaceX construction engineers serve additionally as project managers and supers — this is a construction management role per industry standards. The position is based in Memphis, TN. This role is focused on delivering the electrical backbone — from the high-voltage substation down to the low-voltage racks and BESS — that will power SpaceXSI's Memphis
